Balanced and Unbalanced Forces Review Bell Ringer

Front

What is a balanced force?

Back

A balanced force is when two forces acting on an object are equal in size and opposite in direction, resulting in a net force of zero. The object remains still or moves at a constant speed.

Front

What happens when forces are balanced?

Back

When forces are balanced, the object does not move or continues to move at a constant velocity.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, resulting in a net force that causes the object to accelerate in the direction of the greater force.

Front

What is an example of a contact force?

Back

An applied force is an example of a contact force, as it requires physical contact between the object applying the force and the object being acted upon.

Front

What is the net force when forces are balanced?

Back

The net force is zero when forces are balanced.

Front

What happens when two teams pull with the same amount of force?

Back

If two teams pull with the same amount of force, they will not move at all.

Front

What is the relationship between balanced forces and motion?

Back

Balanced forces do not change the motion of an object; they keep it at rest or moving at a constant speed.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate, change direction, or change its state of motion.

Front

What is an example of an unbalanced force?

Back

If one person pulls a rope with a force of 10 N and another pulls with 5 N, the forces are unbalanced, and the rope will move in the direction of the greater force.

Front

What does it mean for forces to balance each other?

Back

Forces balance each other when they are equal in size and opposite in direction, resulting in no change in motion.
